What a maintenance visit covers
Good maintenance combines a look at the roof with a look at the data. We first compare actual against expected yield: a drop beyond the usual points to a problem long before it becomes visible.
- Modules: broken glass, discolouration, signs of hotspots, soiling
- Mounting: clamps, hooks and rails, corrosion
- Cabling: connectors, routing, chafing, animal damage
- Inverter: error log, fans, display, monitoring connection
How often should a system be serviced?
For most residential systems one inspection a year is enough, combined with regular glances at the monitoring. Commercial systems and systems in exposed locations — near the coast, next to barns, fields or roads — benefit from shorter intervals.
